Non SSO BI URL for users

Hi,

Recently I have implemented SSO with windows AD and it's working fine with below kind of URL and company internal users will use this for SSO.

http://bod-XXX:8080/BOE/BI

Now we have external users where those users cannot use SSO, so planned to provide nonSSO url.

http://bod-xxx:8080/BOE/BI/logonNoSso.jsp

Now management is asking to do customization's to login and logoff pages, I am not sure where I have to implement customization to effect both URL's. I changed image on logon page and the changes were reelected on both URL's.

Is it possible to customize non SSO URL alone, I am planning to make default authentication as 'Enterprise' and hide System and 'Authentication' fields.

Thanks,

Mani
